A method for creating ultra-fine particles of material using a high-pressure mill is described. The method includes placing a material in a first chamber and subjecting the material to a high-pressure fluid jet to divide it into particles. These particles are then transferred to a second chamber in which they are subjected to cavitation to further divide the particles into relatively smaller particles. These relatively smaller particles are then transferred to a third chamber, in which the particles collide with a collider to still further divide them into ultra-fine particles of the material. The mill of the present invention includes a first chamber having an high-pressure liquid jet nozzle, first and second slurry nozzles, a second cavitation chamber and a third chamber which houses a collider. In one embodiment, the slurry nozzle has an inner surface and sharp edges that project slightly out from the inner surface. Sensors may be located throughout the mill to collect data on the comminution process and to use the data to control the resultant particle size. The product size of the ultra-fine particles made according to the mill of the present invention are preferably less than 15 microns. Further, the particles produced using the mill of the present invention are formed as flakes or platelets which have been broken along nature planes in the material.

Thin substrates, such as flat glass panels, are levitated on a porous media air bearing creating a pressurized film of air and preloaded against the air film by negative pressure areas. The pressure can be distributed most uniformly across the pressure areas by defusing the pressure through a porous medium. Such a bearing can be used for glass flattening by holding the glass such that the unevenness is migrated to the side opposite the side to be worked on.

A system for separating solids from a fluid stream. The system includes a first separator device mounted to a container. The container includes a settling compartment and baffle plate module, with the initial settling compartment receiving the fluid from the first separator device. The fluid stream proceeds through the baffle plate module. The solids within the fluid stream will descend to the bottom of the container. A spiral blade is positioned at the bottom of the container, with the spiral blade adapted to convey solids to a first pump member. The speed of rotation of the spiral blade may be varied. The first pump member discharges the slurry to a second separator device. The second separator device will discharge the separated fluid stream into the baffle plate module. In one embodiment, the first separator device is a linear shaker and the second separator device is a cyclone separator and linear shaker mounted in tandem. The fluid exiting the baffle plate module may be directed into a mixing compartment, with the mixing compartment being part of the container. A method of separating solids from a fluid stream is also disclosed.
